COTTON-PICKER.

Specification of Letters Patent.

Patented May 25, 1920.

Application filed March 12, .1919. Serial No. 283,278.

To all whom t may concern.'

Be it known that I, JAMES II. C. Boro, a citizen of the United States, residing in the city of Oklahoma, county and State of Oklahoma, have invented certain new and useful Improvements in Cotton-Pickers, of which the following is a specification. n

My invention relates to further improvements in cotton pickers such as is shown and described in my United States Patent Number 1,305,960 issued June 8,' 1919.

Among the salient objects of the present invention is to provide an improved fan structure in combination with the casing therefor, and the air inlets thereto, whereby greater efficiency is secured; to provide in combination with the revolving tubular member, which carries the fan and is revolved thereby, means for engaging and pulling the cotton out of the boll and thus supplementing the suction action created by the fan for drawing the cotton into and through the nozzle; to provide improved and simplified ball bearing supporting means for said revolving tubular member within the outer casing or body of the nozzle. Other improvements in the details of the construction and arrangement will be evident from the following description taken in connection with the accompanying sheet of drawings, inv which Figure 1 is a side elevation partly in longitudinal section, showing my improved cotton picker;

Fig. 2 is an end view thereof;

Fig. 3 is a cross sectional view taken on line 8-3 of Fig. 1; and

Fig. 4 is a cross sectional view taken on line 4 4 of Fig. 1.

Referring now more in detail to the drawings, my invention as here shown comprises an outer casing or body composed of a iniddle tubular section 1, a cap or noZZleeXtension 2, and a hose-connecting extension 3,

said sections 1, 2 and 3 being screwed to- Y gether, as indicated in a manner to form a smooth joint. A one piece tubular member 4 is rotatably mounted within said body or casing and is provided around its innermost end with a series yof' inclined fan blades 5, which occupy an annularly enlarged portion 1au of said body or casing, as indicated. Said enlarged portion of the casing is provided around its upper side with a series of air inlets 1b, said inlets being in an inclined wall adjacent the fan blades and so posiing ring 8, secured around the tubular member 4, with balls 9 between said ball bearing rings, as clearly indicated. At the upper endl of said body section 1, is another ball bearing ring 10, coperating with afball bearing ring 11, secured around the tubular member 4, with balls 12 therebetween, asy indicated.- An adjusting collar 13 is'screwed into the upper end of the body section 1 before section 2 is attached thereto. The upper end of the tubular member 4 is provided with inwardly projecting prongs 14, adapted to engage the cotton and to assist in pulling it out of the bolls. The end of the body section 2, is turned inwardly, as at 2, to overhang the end of the tubular member 4, as indicated. This provides an inlet of less diameter than the tubular member 4. The hose connecting end 3, of the casing, it will be noted, is of a diameter corresponding to the diameter of the tubular member 4. Thus I have improved and simplified my cotton picking devicelin a manner which makes it more eiicient in its cotton picking action, and also which f ports adjacent said enlarged portion, said' casing having a joint around said enlarged portion whereby to be separated at will, an inner tubular member revolubly supported in said casing and provided at one end be-V low its point of support and, within said annularly enlarged portion, with a series of fan blades, said fan blades being interposed between said air inlet ports and the end of said device to be connected with exhaust means, and ball bearing means interposed between said inner tubular member and the inside of said casing, only at points between the intake end of said device and said inlet ports, whereby to avoid the passing of air and dust through said ball bearing means.

2. In a cotton picking device of the character referred to, a tubular casing having one end adapted for connection with a pipe ing means interposed between said innerr tubular member and the inside of said casing at points between said inlet openings and the intake end of said device, whereby to protect said bearings rfrom inrushing air and dirt, substantially as described.

3. In a cotton picking device, a body composed of three sections detachably secured together, the middle section being provided at one end with an annular enlargement having air inlet openings through one side of said enlargement, a tubular member revolubly supported in said body and provided around one end within the annular enlargement of said body with a series of fan i blades, positioned to one side said 'air inlet openings, ball bearing supporting means 1nterposed between the opposite ends of the middle sectiony of said body and said tubu- V lar member, for revolubly supporting said tubular member, whereby the two end sections. of said body may be detached from said middle section without interfering with said ball bearing` means or said tubular member, substantially as described.
